This paper proposes a model of neural tree architecture with probabilistic neurons. These trees are used for classification of a large amount of computer grid resources to classes. The first tree is used for classification of hardware part of dataset. The second tree classifies patterns of software identifiers. Trees are implemented to successfully...
This paper analyses basic concept of elastic cluster as a hybrid solution of high-performance computing tasks for computing grid and cloud. The analysis is focused on the context of managing resources and tasks in the elastic cluster. In this work design, model and implementation of scheduling algorithm is described. The scheduling algorithm is bas...
This work is focused on the issue of job scheduling in a high performance computing systems such as grid, cloud or systems with hybrid environments. The goal is based on the analysis of scheduling models of tasks in grid and cloud, design and implementation of the simulator on the base of GPGPU. The simulator is verified by our own proposed model o...
Methods of data manipulation in combination with sturcture of the data and integrity constraints define data model used in the relational databases. This article focuses on the methods and processes of operation sets which are used for selection of data from relational database and translation between various formats of this manipulation. The artic...
This article presents methods for correct decomposition for high performance computations related to large sets of graphs. These computations contain large number of calls of sequential, recursive algorithm for NP-complete problem - proper edge coloring of graph. Decomposition of this computational problem is not trivial, since the number of recurs...

poznačenom pandémiou koronavírusu vzniklo v spolupráci
s ďalšími informatickými pracoviskami na Slovensku množstvo
inovatívnych metodík pre ZŠ a SŠ, niekoľko uče...
This paper deals with tuning of proportional-derivative (PD) and "intelligent" proportional-derivative (iPD) controller for the double integrator plus dead time (DIPDT) system. iPD corresponds to a PD controller augmented with a disturbance-observer based integral (I) action based on finite impulse response (FIR) filter. Since noise reduction requi...
The paper discusses approaches and results achieved by the performance portrait method in optimal and robust tuning of proportional-integrative-derivative (PID) controllers for the double integrator plus dead time (DIPDT) models. It extends results achieved in tuning proportional-integrative (PI) controller for the integral plus dead time (IPDT) pl...

Microcontrollers are becoming more and more popular at people of all ages. Microcontroller Arduino is widespread in the world. As it turned out at our Department of Computer Science, learning Arduino for beginners is sometimes difficult because working with Arduino requires some knowledge of hardware parts and programming skills. For beginners we t...
Článok popisuje najmä robotiku na informatickom krúžku pre deti z druhého stupňa základných škôl. Budúci učitelia informatiky a študenti aplikovanej informatiky sú na krúžku lektormi sprevádzajúci žiakov. Hlavným cieľom je poskytnúť budúcim učiteľom a študentom aplikovanej informatiky možnosť vzdelávať a nadobúdať skúsenosti so žiakmi zamerané hlav...
V tomto článku prezentujeme výpočtové myslenie ako proces riešenia úloh, ktorý pozostáva z metód riešenia úloh a intelektuálnych postupov. Pričom sa zameriavame na dekompozíciu problému, hľadanie rovnakých vzorov, tvorbu modelu, vytvorenie algoritmu a overovanie riešenia problému. Výpočtové myslenie nám umožňuje pochopiť komplexný problém, dekompon...
The paper is motivated by critical demand for experts and scientists working in areas of mathematical modeling, simulations, big data techniques and who are familiar with management of HPC systems from user and administrator point of view. We created a new course entitled “HPC system management”. Our goal is focused on students to provide them with...
In this article we deal with computational thinking as the contribution of informatics in everyday human life. Computational thinking is a process of solving problems (tasks), which consists of methods of problem-solving and intellectual practices. The importance of developing computational thinking is demonstrated with a simple example. An example...
This work focuses on the issue of a high performance computing education based on systems such as grid, cloud, HPC cluster or systems with hybrid environments. The goal is based on the analysis of the High Performance Computing Strategic Research Agenda in Europe and the published findings in USA in context of needs for education and training speci...
Contributing student pedagogy requires students to produce artifacts (contributions) for the purpose of contributing to other peers’ learning, and encourages students to value these peer contributions. A free web-based tool called PeerWise was created by Paul Denny at the University of Auckland to provide support for the implementation of contribut...
